I have an array of images like this:

int fruitList = new int 
 R.drawable.apple,
 R.drawable.orange,
 R.drawable.bannana
;

and an ImageView. For every fruit i want to a) populate the ImageView b) wait for click to open a Dialog (Choose fruit name and do something ...) and repeat for next fruit.

I thought of a for loop but doesn't make sense. I need to wait for the click before going to the next fruit.

Any ideas ??

1. Hold an index for your position along the fruitList


2. Set an onClickListener on the Image View.


3. Create a Dialog in the onClickListener


4. 
   Subscribe any clicks in the dialog, and in that subscription change the fruit by incrementing your index (maybe % fruitList.size?)


5. In the onClickListener launch the dialog

The key difference between app development and smaller programs is that apps are all event based. A for loop isn't suited for this kind of task.

You can use Carousel view for it. You can use following repositories for it. Choose what you want
